The 2002 4.3L has an EGR valve, at least mine does.
look om the passengers back side of the valve cover. You need to take off the vortec cover.
The EGR (Exhaust Gas Recirculation) valve on a 2002 Safari van with a 4.3-liter Vortec engine is located on the intake manifold, typically on the driver's side. It is mounted near the rear of the engine, accessible from the engine bay. To reach it, you may need to remove some components for better visibility and access.
Low fuel pressure, bad IAC valve, vacuum leak, bad injector(s). You also need to check the EGR valve.
The PCV (Positive Crankcase Ventilation) valve on a Vortec 4200 engine is located on the valve cover, typically on the driver's side. It is usually integrated into a grommet or fitting that can be easily accessed for replacement or inspection. To reach it, you may need to remove any obstructing components, such as the engine cover or intake ducting.
The PCV valve on a 2002 Pontiac Bonneville is located on the back of the in take manifold, however to get to the PCV valve you will need to remove the valve cover.
The egr valve on the 2002 explorer is on the right rear corner of the intake. The throttle body will need to be removed to access it.
Need to know which one you are looking for or, what does this vacuum control valve control.
Way to flat of a question and you need to reword and be more precise. Are you talking vortec as in the turbos? Or vortec in throttle body spacers? Or vortec heads? Or some kind of weird science geek experiment?
It will progress to terminal stage heart failure
on top of the manifold under the plate that says"PCV VALVE" you will need to remove two 10mm bolts...
Toyota Camry does not have adjustable valves. If valve clearance is not proper you need to replace the valve shims with appropriate sizes (usually different for each valve).
No because the ports on a tbi head are different than the ports on a vortec head, vortec heads need a vortec intake however you can switch a carburated engine to a tbi engine because the heads are the same
